This announcement may help Nvidia to work around a standoff with Intel over whether Nvidia can make chipsets that work with Intel's next-generation Nehalem platform, due later this year. And also demonstrates that despite Nvidia CEO Jen-Hsun Huang' s rhetoric, Nvidia must cooperate with Intel in order to thrive.

Monday's announcement has no relation to separate licensing negotiations, according to sources familiar with the discussions. In other words, Nvidia is not announcing a chipset for Nehalem--which would require a license. It is simply a statement that Nvidia will support Nehalem with its nForce 200 Scalable Link Interconnect (SLI) chip.

However, some reports say Nvidia has reached an agreement with Intel to license Intel's Quick Path Interconnect (QPI) technology, paving the way for Nvidia to design chipsets for Nehalem.

The nForce 200 chip will work with Intel's "Bloomfield" line of Nehalem processors and the accompanying Intel chipset. SLI allows Nvidia to use multiple graphics boards in one system.

Upcoming SLI motherboards will use Nvidia nForce 200 SLI silicon, Intel Bloomfield processors, and Intel Tylersburg (X58) chipsets, Nvidia said in a statement.

"The nForce 200 SLI processor features patented SLI technology for graphics bandwidth management and multi-GPU peer-to-peer communications, both required to optimize graphics performance," Nvidia said. GPU stands for graphics processing unit.

Future systems "can be powered by one, two, or even three Nvidia GeForce GPUs, including the new...GeForce GTX 280 and GTX 260 GPUs," according to Nvidia.

Nvidia included statements from system suppliers in the Monday release. "It's great to see that Nvidia opted to enable SLI on the future Intel Bloomfield platform," said Rahul Sood, CTO Voodoo Business Unit, HP. "Make love not war I say...and Nvidia's (enabling) of Intel chipsets to support SLI will make our jobs much easier."

Nvidia claims that nForce 200 SLI silicon with Intel's new Bloomfield processor and Tylersburg chipset core logic chipset will deliver up to a 2.8X performance boost over traditional single graphics card platforms.

Motherboards and PC systems that will use the Nvidia nForce 200 SLI chip, Nvidia GeForce GPUs, and Nvidia SLI technology will be available from companies such as Acer, ASUS, Dell, Falcon Northwest, Legend, and Velocity Micro.

Nvidia video: No quad-core chip needed for extreme PC

Nvidia has posted a video that involves the new GTX 280 chip, overclocking, lots of liquid nitrogen, and the Nvidia labs. Oh, and no quad-core processor. Get the point?

"A lot of people believe you need an Intel quad-core or Intel quad-core Extreme to build an extreme PC," says the post by "Steffee" on the Nvidia Web site. "Today I'm going to build a gaming PC using the Intel Core 2 Duo. That's duo. Got that? Duo, two cores."

I think the point the blogger is trying to make is that the test system has only has two cores, though I could be mistaken.

Here's an excerpt from the blog: "Think you need a quad-core CPU for an extreme gaming PC with impressive 3DMark Vantage numbers and gaming performance?...I overclocked and hyper-cooled an SLI gaming rig using two of our latest and greatest GPUs--GeForce GTX 280...and a sub-$200 CPU."

Intel, of course, has a different take on this. "Most of what people do today with their computers requires powerful processors. Examples of processor-intensive applications include: creating content, viewing/editing high definition video, using social media sites, office tools, downloading music, and editing photos," Intel said in a statement.

In the test, the blogger uses an NForce 790i Ultra SLI motherboard, Intel core 2 duo E8400, in addition to the GTX 280 graphics card.

With the single GTX 280 board, the score is a 3DMark Vantage "X4796."

Then the blogger (an Nvidia employee) takes a hike to the Nvidia lab. "Now we're going to take a field trip to Nvidia labs to do some serious overclocking," she says. After adding what seems to be prodigious amounts of liquid nitrogen and adding another GTX 280 SLI board, the 3DMark score jumps to "X10,282."

Intel could respond (which it hasn't) by saying that the E8400 is not a slow processor: it runs at 3.0GHZ and has 6MB of cache. And overclocked with liquid nitrogen, it would probably get some pretty good scores too. And then, of course, it might be simpler to just get a quad-core Extreme CPU.

In the test, the Nvida GTX 280 core clock was overclocked to 727MHz and the shader to 1458MHz. The core clock is normally 602MHz and the shader clock 1296MHz.

System specifications:
--2× NVIDIA GeForce GTX 280 graphics cards running in SLI nForce 790i Ultra SLI motherboard
--Intel Core 2 Duo E8400 CPU
--4 GB SLI-ready Corsair DDR3 memory
--PC Power and Cooling TurboCool 1200W power supply
--Windows Vista 32-bit operating system

Intel and Nvidia headed for licensing standoff

by Rich Brown
  • 2 comments

This started out as a rumor today, but Intel has since more-or-less confirmed that licensing discussions between Intel and Nvidia for Intel's next-generation processors are not going well and the resulting conflict could have implications for high-end gaming PCs.

chip design

The story is that Intel and Nvidia are currently negotiating technology licenses for Nehalem, Intel's next-generation desktop CPU due out at the end of this year. As we were told from multiple desktop vendors who wish to remain nameless, Intel wants to license SLI from Nvidia for its Nehalem chipsets, and if Nvidia won't, Intel will withhold the license that would enable Nvidia to support Nehalem's memory controller, and thus Nehalem, on its own chipsets.

We have no official confirmation from Nvidia on this, and Intel's statement from PR manager Dan Snyder is vague, but it lends credence to the story:

"There is a disagreement between Intel and Nvidia as to the scope of Nvidia's license from Intel to make chipsets compatible with Intel microprocessors. Intel is trying to resolve the disagreement privately with Nvidia and therefore we will not provide additional details. It is our hope that this dispute will be resolved amicably and that it will not impact other areas of our companies' working relationship."

Intel has been after SLI support for its chipsets for years, but has thus far only been able to build it into its ultra high-end Skulltrail motherboards, seemingly a one-off. With SLI available across all of its chipset lines, Intel would be able to sell motherboards that support both AMD's and Nvidia's multigraphics card technologies. Right now Intel boards (with the exception of Skulltrail) only support AMD's CrossFire.

Nvidia, on the other hand, has kept SLI close, often citing compatibility and certification concerns as the reason why no other chipset vendor has been able to offer SLI-capability. But if Nvidia loses out on Nehalem for its next-generation chipsets, the high-end desktop market will become more fragmented than it's been in years. Nvidia has been able to offer SLI-supporting chipsets for both AMD and Intel processors, but if this split happens, on one side we'll have Nehalem and CrossFire-based systems, the other will offer SLI (and possibly CrossFire, if hacks used in the past continue to work) and AMD CPUs.

In light of this rumor, Nvidia's recent marketing push encouraging upgraders to pick a graphics card before a quad-core CPU takes on new significance. If Nvidia knows high-end PC gamers will have to make a choice later this year, better to plant the seeds in its favor early. Intel probably has less to worry about, because gamers who demand SLI with a fast Intel processor can still use Nvidia's NForce 790i chipset, which supports the current generation of Intel Core 2 Extreme chips.

UPDATE 5:48pm PT - Intel released an additional statement after this blog was posted. "We are not seeking any SLI concession from Nvidia in exchange for granting any Nehalem license rights to Nvidia," the company said.

Nvidia's Hybrid SLI: Power when you need it, efficiency when you don't

by Matthew Elliott
  • Post a comment

Nvidia apparently has an answer to AMD's Power Xpress hybrid graphics technology. AMD announced last December that its forthcoming Puma mobile platform (due in the first half of 2008) will introduce Power Xpress, which lets laptops switch between discreet graphics when plugged in and integrated graphics when running on battery power.

According to reports, Nvidia is working on a similar but slightly different dual-graphics solution it's calling Hybrid SLI. When running on battery power, Hybrid SLI, like AMD's Power Xpress, will run solely on integrated graphics. When connected to a wall socket, however, both the discreet graphics and the integrated graphics will be put to use. One potential use for the integrated graphics chip in this scenario would be to carry out physics calculations while the graphics card(s) are busy pushing pixels.

While AMD is concentrating solely on the mobile market for its Power Xpress technology, Nvidia is looking to put Hybrid SLI in both laptops and desktops. The benefit for laptops, of course, is improved battery life for systems with power-hungry, discreet graphics. For desktops, Hybrid SLI can not only help lower electric bills but also boost performance by letting the integrated graphics assist the dedicated graphics with demanding applications, including 3D games. According to the report, Nvidia is set to release Hybrid SLI in the "coming year."
